BACKGROUND

Mobile machinery such as agricultural tractors, bulldozers, tracktractors, skip loaders, all-terrain vehicles and earth grading tractors,generally referred to as a “tractor,” typically are provided with asuitable power plant, a source of fluid under pressure and or a sourceof electric current. The fluid pressure source includes suitable valvecontrol means. The tractors typically include an implement mountingsystem known as a three-point hitch. The three-point hitch includes apair of opposed spaced apart lateral bottom-link arms located at therear of the tractor body or frame rotatably connected to the tractorwith ball joints which are affixed to the frame or body of the tractorat a selected distance of typically 12 to 30 inches above the ground andextend on each side of a center draw bar. The free distal ends of thearms typically include a ball rotatable in a socket with an axial holeextending there through.

A third arm, called a top-link arm, is also rotatably connected with aball joint to the tractor frame at a point about 30 to 60 inches aboveground and centered above the bottom-link arms. The free distal end ofthe top-link arm is fitted with a rotatable ball with an axial holeextending there through for connecting to a center point on an implementin alignment with studs. Free ends of the two bottom-link arms and thetop-link arm provide three-points of attachment to implements andtherefore is referred to as a three-point hitch. The length of top-linkarm is generally adjustable by means of a built in turn-buckle assembly.This provides for manual leveling of the attached implement. Thetop-link arm turn buckle assembly can be replaced with a hydrauliccylinder for quick controlled manual or automated adjustments of thelength of the top-link arm resulting in adjustments of the attachedthree-point implement.

The bottom-link arms are connected to a lift-link arm to provide a meansfor lifting such as a suitable power lift mechanism, for example one ormore hydraulic cylinders. This provides the capability to raise andlower the two bottom-link arms and thus the implement which is connectedto the three-point hitch. Because the free ends of all three arms areconnected to the tractor with ball joint type connections, all threearms may freely pivot to the left and the right any time the three-pointhitch has the implement raised off the ground. On older tractors, anadditional bar called a stabilizer arm is provided, if desired, and isconnected to one of the first two bottom-link arms and to a fixed pointon the tractor. On newer tractors, two stabilizer arms are provided, onefor each bottom-link arm and they are also connected to a fixed point onthe tractor. The stabilizer arms allow the bottom-link arms to still beraised and lowered by hydraulic means, but the implement is held stablewith reference to the horizontal plane, and cannot swing to and fro asbefore.

The attached implement can include a transversely extending tool bar orframe member having laterally spaced apart studs extending from thefront tractor-facing side of the implement for removable attachment tothe sockets held within the distal ends of the bottom-link arms. Inaddition to the bottom-link arm attachment hardware means is an upperattachment hardware means for the attachment of the top-link arm.

A three-point hitch is standard equipment on most agricultural and earthgrading tractors. The use of a three-point hitch provides lifting,lowering and tilting mechanisms to attached agricultural implements,such as agricultural implements. The tractor three-point hitch allowsthe attached tool or implement to be raised and lowered, tiltedhorizontally and tilted vertically, all such movements and adjustmentsprovided by hydraulically activated cylinders or manual crank screwdevices. Front three-point hitches, while available, are less commonthan rear three-point hitches on agricultural tractors.

The three-point hitch provides for a quick attachment of variousimplements needed on a tractor. In addition, when the implement is inthe raised or lowered position, lateral movement of the three-pointbottom-link arms is freely available. To limit lateral movement of theimplement in the raised or lowered position, the user can add astabilizer arm comprising a longitudinal member having a selectedadjustable length attachable to a swing arm attachment point on thetractor body or frame with the opposing end attaching to the sameimplement stud as the adjacent swing arm to limit lateral movement ofthe bottom-link arms. Many tractor brands are now factory supplied withthree-point hitch bottom-link stabilizer arms. Controlled lateralmovement of an attached implement is not provided with a three-pointhitch.

Earth-moving equipment in the construction and farming field has rapidlychanged for the better in recent years with the introduction of GlobalPositioning Systems (GPS) and laser guidance systems. Current GPSguidance systems for earth-moving and agricultural tractors generallyare designed to auto-steer the tractor. Much of the guidance involvessteering the tractor in a straight line to form a straight road orstraight row of crops. Since most agricultural and earth gradingtractors are steered by the front end of the tractor, the rear endmounted three-point hitch attached implement may not align in a straightline with the front steered end of the tractor. This misalignment wouldnormally occur while the tractor is turning 180 degrees around at theend of the crop row and then joining onto the next crop row in the otherdirection. This misalignment would also occur while the tractor is inthe middle of the crop field and the tractor veered slightly off line ofthe crop straight line forcing the tractor operator to correct thesteering of the tractor. This steering correction of the tractor canalso shift the rear end of the tractor in the opposite direction of thesteering correction causing the rear three-point connected implement toalso veer off course of the straight crop row and possibly damage thecrops while cultivating the field or misalign the crops while planting.Lasers have come into play in the earth-moving and agricultural fieldmostly by controlling grade leveling implements on the tractor in an upand down motion for achieving a level or sloped grade.

Conventional laterally moving implement toolbars pivot on four parallelsupporting arms extending out from the front of the supporting frame.Short sized supporting arms provide limited lateral movement of thetoolbar section of the implement. The short lateral movement isexacerbated by the positioning of the tool mounting bar being too closeto the frame structure that mounts to the tractor three-point hitch.Mounting brackets further decrease the tool mounting bar clearance tothe frame structure. Pivoting-support-arms pivot in either directionlimiting the length of the lateral movement to much less than the lengthof the pivoting-support-arms. The weight that thesepivoting-support-arms can support on the toolbar with heavy implementsis dependent on the strength of the pivot arms and their pivot joints.The pivot joints need to sustain a tremendous weight load when handlinga heavy implement as they pivot side to side. This weight load iscompounded and increased if the pivoting-support-arms are increased inlength.

Two-point hitch configurations present a different set of limitationsfor use of lateral connection devices. The three-point hitch inventiondiffers from a two-point hitch in the mounting ability by utilizing theadvantage of the top-link arm attachment to the tractor frame, theimproved locations for the sleeves that provide the sliding housings, amore versatile and stable two tier stacked movable implement attachmentsection compared to the one movable toolbar and a more stable andfunctional two or more tiered stacked movable implement attachmentsection compared to the one movable implement attachment section.

Existing systems for pulling or pushing implements suffer from asignificant disadvantage, particularly that the implement can go offcourse, particularly during turns. This can result in destroyed crops,inadequate application or over application of chemicals used for crops,unplowed soil, and other deleterious effects. These problems can occureven when the mobile machinery, such as a tractor, is on course.

Therefore, there is a need for a system that can allow an implement tobe pushed or pulled that helps maintain the implement on track, evenwhen the mobile machinery used for pulling or pushing the implement isoff track.

SUMMARY

A system according to the present invention that satisfies this needincludes a connecting apparatus suitable for connecting an implement toa three-point hitch of mobile machinery, such as a tractor. Theconnecting apparatus comprises a first framework disposed in a firstplane and comprising at least two parallel, vertically spaced-apart,laterally extending rails. Three attachments are supported by the firstframework for attachment to the three-point hitch. The slidable secondframework is generally in the plane of the first framework and ismounted on the rails to slide laterally along the rails. At least twoconnectors, and typically three connectors, are supported by theslidable second framework for connecting the slidable second frameworkto an implement that can be pulled or pushed by the mobile machinery. Atleast one driver, and for a robust apparatus, two drivers, are connectedto the first framework and connected to the second framework for drivingthe slidable framework laterally back and forth along the rails.

In use of the apparatus, the position of the implement relative to themobile machinery is changed by the action of the driver, the driverlaterally moving the second framework.

Typically, the first framework comprises an upper cross beam and a lowercross beam, each cross beam substantially parallel to the rails. In apreferred version the first framework comprises at least two rails, atleast two vertically extending studs, the upper cross beam, and thelower cross beam. The upper cross beam can support one of theattachments and the lower cross beam can support two of the attachments,typically in a triangular configuration.

The driver can be at least one hydraulic cylinder or at least oneelectric linear actuator.

When a cylinder is used as part of the driver, the cylinder can beprovided with a stop for limiting lateral movement of the secondframework. The driver can be manually or automatically controlled. Themanual control can be a lever or the like. Also a switch can be providedfor switching between manual and automatic control.

Preferably there is a guidance system for automatically controlling thedriver to position the slidable second framework in a predeterminedpathway. The guidance system can comprise a GPS receiver, an underground(buried) or above ground guidance wire, or a position signal receiverfor receiving a laser signal. The guidance system can comprise at leastone GPS positioning receiver mounted on the second framework forreceiving signals from the satellites or ground mounted base relaystation to determine the position of the slidable second framework, anda controller for receiving position signals from the position signalreceiver, the controller adapted to control the driver to position theslidable second framework in the predetermined pathway. The GPS guidancesystem utilizes data input into a data input monitor to set thepredetermined coordinates of the mobile machinery and the connectingapparatus. GPS guidance can control the mobile machinery steering inaddition to the connecting apparatus position. GPS positioning of theconnecting apparatus in conjunction with GPS steering of the mobilemachinery is an advantage over GPS steering of the mobile machineryalone while attempting to guide an attached implement along apredetermined pathway. In a guidance wire application, the guidancesystem can comprise at least one sensor mounted on the second frameworkfor receiving signals from the guidance wire. The apparatus can comprisea position signal receiver supported by the slidable second frameworkfor determining the position of the slidable second framework, and acontroller for receiving position signals from the position signalreceiver, the controller adapted to control the driver to position theslidable second framework in the predetermined pathway. The guidancesystem can comprise at least one laser position receiver for receiving alaser signal from a rotating vertical laser transmitter, and acontroller for processing position signals from the position signalreceiver, the controller adapted to control the driver to position theslidable second framework in the predetermined pathway. In a laserguidance application, generally there is no need for data entry into adata entry monitor. The position of the laser receiver on the connectingapparatus can position the connecting apparatus and steer the tractor iftractor steering is preferred.

The second framework can comprise at least one sleeve for sliding on atleast one rail, and typically multiple sleeves for sliding on multiplerails.

To power the driver, the apparatus can include a power receptacle forreceiving power from the mobile machinery, which can be electric poweror hydraulic fluid power.

For implements that have more than three places for connection, therecan be more than three connectors, such as four or more connectors.

To assist an operator of the mobile machinery, the apparatus can includea light fixture and at least one camera.

In a preferred version of the invention, for robustness, the firstframework comprises four rails, and the second framework comprises fourlateral substantially parallel sleeves connected at their ends by endposts, each sleeve slidable on one of the rails.

It is preferred that there be positioning indicia on the upper crossbeam of the first framework for positioning the second frameworkrelative to the first framework. This same type of positioning indiciacan be used on the lower cross beam of the first framework. Also, therecan be positioning indicia on one or more of the sleeves for adjustingthe position of any connector supported by the sleeve.

Preferably the apparatus includes a sensor for sensing the position ofthe second framework relative to the first framework. This can becombined with an alert generator that generates an alert, such as asound or flashing light, when the sensor senses that the secondframework slides beyond a predetermined position.

Preferably the apparatus includes a plumb gauge and a level gauge forcorrectly adjusting the attitude and positioning of the implement.

Preferably at least one connector is laterally adjustable on the secondframework. Also preferably at least one connector is verticallyadjustable on the second framework.

Additionally, the apparatus can include a connection guidance system forconnecting the apparatus to the implement, the connection guidancesystem comprising a sensor on at least one, and preferably at least two,connectors for sensing the position of the implement. With theconnection guidance system, the system can include a method forconnecting the apparatus to the implement, where the implement hashitches for connector with the connectors. The method comprises placingthe implement and apparatus approximate to each other, determine thealignment of the connectors and the hitches, and adjusting the alignmentby sliding the second framework relative to the first framework.

The invention also includes a system where the mobile machinery, theapparatus described above, and an implement are connected together, withthe apparatus attached to the mobile machinery via the three-point hitchon the mobile machinery, and the implement attached to the slidablesecond framework with at least two connectors.

The system can also include a pair of support stands for supporting theapparatus when the apparatus is otherwise not well supported, such asnot being attached to all three points of a three point hitch, eachstand comprising pins for engaging corresponding holes in the verticalstuds of the first framework. Clips can be used for holding the pins intheir engagement position.

Multiple connection apparatus of the present invention can be daisychained together such as having a central apparatus attached to themobile machinery, and having an additional pair of the apparatus, eachone of the pair pivotally and removably attached to the sides of thecentral apparatus. Each of the pair can be modified from the centralapparatus such as for the driver location and driver connection betweenthe first and second framework. Each of the outer pair is typicallydesigned to carry lighter duty implements than the central apparatus.

FIG. 1a shows the positions of a front and rear three-point hitch asthey are combined with a tractor 38 in the prior art. This side viewshows a Carry-All implement 300 mounted to the front and rearthree-point hitches of a tractor 38. Shown are the three points ofattachment of a three-point hitch to the Carry-All implement 300 usingtwo bottom-link attachment arms 318 and a top-link attachment arm 324.Two bottom link attachment arms 318 (see FIG. 2) are generallypositioned on the same horizontal plane unless an application of userequires otherwise. Lift link arms 330 are visible on the frontthree-point hitch while not being visible on the rear three-point hitchbeing hidden by the larger rear tires. In many farming and excavatinginstances a rear three-point hitch is used by itself without a frontthree-point hitch being attached to the tractor 38. Using a combinedfront and rear three-point hitch can increase the efficiency of thefarming or excavation application if used properly.

FIG. 1b shows schematically a system according to the present inventioncomprising a first connecting apparatus 40 attached to the front andrear three-point hitches of a tractor in addition with the Carry-Allimplement 300 mounted to the first connecting apparatus 40 at front andrear locations. The connection apparatus 40 mounts first to thethree-point hitch of the tractor and the Carry-All implement 300 nextmounts to the connection apparatus 40.

FIG. 1c shows a close-up side view showing a tractor with the connectionapparatus 40 mounted to the rear three-point hitch of a tractor with theprior art Carry-All implement 300 mounted to the connection apparatusshowing top-link arm 324 attaching to the rigid-frame top-linkattachment 66, and the bottom link arms 318 attaching to the rigid-framebottom-link connection points 68 of the connection apparatus 40. Slidingframe bottom-link quick hitch hook and stop bar 136 attaches the lowerportion of the Carry-All implement 300 to the sliding-frame 46 andsliding-frame top-link hook and stop bar 130 attaches the upper portionof the Carry-All implement 300 to the sliding-frame 46. The slidingframe can be guided with a system using a buried guidance wire 141utilizing a signal generator 143 to activate the guidance wire 141.

FIG. 2 shows the prior art implement 300, that includes a top attachmentreceiver 312 which usually comprises a pair of spaced apart alignedprojections or flanges centrally disposed and having a hole therethrough for receiving a distal end 326 of the top-link arm 324 which isreleasably held thereto by a pin or bolt 310. The distal end 326 cancomprise a socket. The opposing end 322 of the top-link arm 324 alsocomprises a distal ball socket for attachment to the tractor top-linkattachment location with similar spaced apart projections and retainingpin or bolt. The implement 300 typically includes a transverselyextending tool bar or frame member having laterally spaced apart studs314 extending from the tractor-facing side of the implement frame forremovable attachment to the bottom-link arm 320 sockets held within thedistal ends of the bottom-link arms 318. In the alternative, laterallyspaced apart studs 314 are replaced with two flanges with axial centeredholes 195 (see FIG. 24) with a pin therein for connection to thebottom-link arms 318. The distal end 326 of the top-link arm 324 anddistal ends 320 of the two bottom-link arms 318 contain within socketshaving rotatable balls including apertures extending there-through forinsertion of pins for connecting these three ends to fixed points on theimplement. The top-link arm 324 includes a turn-buckle assembly withthreaded rods and a threaded hollow cylinder which can be rotated tolengthen or shorten the overall length of the top-link arm 324.

FIGS. 3 shows prior art lift-link arms 330 connect at lift-link armsconnection to bottom-link arms 332 that cause the bottom-link arms 318to rotate upward and downward pivoting the proximate ends of thebottom-link arms on a spindle and raising the distal end of thebottom-link arms 320 and the implement attached thereto. The top-linkarm 324, in turn, causes the upright portion of the carry-all implement300 to maintain general uprightness or verticality. Consequently, thehorizontal portion of the implement remains generally horizontalthroughout the upward and downward motion of the carry-all implement 300(see FIG. 2). Because the bottom-link arms 318 points of attachment tothe tractor under-carriage location 316 are also ball and socketarrangements, the implement is free to move laterally a fixed distanceproviding “play” for with respect to the tractor. In some situations,this freedom of movement is desirable, and in other situations,undesirable. As in the case of this present invention, the freedom ofmovement situation is undesirable, additional stabilizer arms areconnected, one to each of the bottom-link arms. One end of thestabilizer arms connected approximately half way down the length of eachbottom-link arm 338, the other end is connected to a fixed point on thetractor under-carriage location 334 which is coaxial with the twobottom-link arm connections to the tractor under carriage at location316. This allows full up and down movement of the implement but removesany random lateral motion of the implement. The stabilizer arms 336 maybe a turn-buckle assembly with threaded rods and a threaded hollowcylinder which can be rotated to lengthen or shorten the overall lengthof the stabilizer arm. In the alternative, the stabilizer arms may be arigid arm with an adjustable threaded screw device located at thebottom-link arm location 338. Another alternative to the above statedstabilizer arms is one or two stabilizer arms connected to a rigid pointon the tractor and the other end connected crossways to one or both ofthe bottom-link connection pins 314 (see FIG. 2) to the implement.

Bottom-link arms 318 support the weight of the implement. Lift-link arms330 attach between the bottom-link arms 318 and tractor hydraulicactuated lift arms at connection point 328. The adjustable top-link arm324 attaches to the tractor mounted top-link bracket 340 with aremovable pin or bolt thru the top-link arm distal end 322, which canhave a mounted rotatable ball, while the opposed distal end 326 of thetop-link arm has a rotatable ball and attaches to a top-link attachmentplate 312 on the implement as shown in FIG. 2. A Power Take-Off shaft(PTO) (not shown) can be disposed centered on the rear of the tractorthrough the PTO pathway 98 in a plane between the height of the top-linkattachment plates 340 on the tractor and the bottom-link attachments 316to the tractor.

FIG. 5 and FIG. 6 show the tractor-facing side of the laterallyadjustable three-point hitch implement attachment, of a first version ofthe invention, comprising a rigidly-mounted base frame 45 (also referredto as a first framework), and a slidably-mounted frame 46 (also referredto as a second framework). The rigidly-mounted base frame 45 isconfigured for connection to the bottom-link arms 318 and top-link arm324 of mobile machinery, such as the tractor 38 (see FIG. 1a ).Connections from the tractor to the rigidly-mounted base frame 45 occurat the top link attachment 66 and at the two bottom-link attachment 68.The rigidly-mounted base frame 45, also referred to as the first frame,has at least two parallel, vertically spaced apart, laterally extendingrails. In the version shown in FIG. 5 and FIG. 6, the first frame 45comprises four tiered horizontal longitudinal frame member rails 48, 49,50, 51, which can be solid or hollow and any suitable shape incross-section, rigidly connected at the ends to at least two verticalsupport members, also referred to as studs, and capable of beingremovably secured to the three-point hitch of the tractor. Preferably inthe design of the rigidly-mounted base frame there are at least twoupper and two lower horizontal frame members providing an opening ofsufficient size between the upper and lower horizontal frame members toaccommodate a Power Take Off “PTO” driveline if required for theattached implement. The PTO opening arraignment is shown in FIG. 7 usinga double driver configuration allowing for the space needed for the PTOdriveline to connect to an implement. FIG. 5 and FIG. 6 show three upperand three lower horizontal frame members for the rigidly-mounted baseframe showing the rigidly-mounted base frame with six horizontallongitudinal aligned frame members, wherein frame member 47 (alsoreferred to as upper cross beam), 48 and 49 are in an upper position andframe members 50, 51, 52 (member 52 is also referred to as lower crossbeam), are in a lower positions, and four vertical frame members. Framemembers 53 and 54, also referred to as studs, are positioned to one sideof the rigidly-mounted base frame and frame members 55 and 56 arepositioned to the opposing side of the rigidly-mounted base frame.Members 53, 54, 55, and 56 are also referred to as studs. Members 48,49, 50, and 51 are also referred to as rails. The laterally adjustablethree-point hitch implement attachment apparatus 40 has square shapedhorizontal sliding-frame members 57,58,59,60 (also referred to assleeves) and square shaped horizontal rigid-frame members47,48,49,50,51,52 oriented in a diamond shape with all sides placed atforty-five degree angles as compared to a horizontal plane. By squareshaped this is with regard to a vertical cross section and preferablythey are oriented with a corner facing upwardly.

The slidable-mounted frame 46 comprises at least two horizontallongitudinally aligned hollow frame member tubes securely and sturdilyconnected at the ends with at least two vertical frame members forming agenerally rectangular sturdy frame that is transversely andslidably-mounted on at least two horizontal longitudinal frame members,bars or rails of the rigidly-mounted base frame 45 enabling theslidable-mounted frame 46 to travel transversely, also referred to aslaterally, across from one side to the other side of the rigidly-mountedbase frame 45. FIG. 5 shows two upper and two lower horizontal hollowframe members for the slidably-mounted frame, wherein frame members 57and 58 are in the upper positions and frame members 59 and 60 are in thelower positions. They slide on the rails of the base frame 45. Shown inFIG. 5 are four vertical frame members, two vertical frame members 61and 62 are positioned to one side and frame members 63 and 64 arepositioned to the opposing side. Frame members 61-64 are also referredto as posts. Four hollow horizontal slidable-mounted frame members asopposed to two hollow horizontal slidable-mounted frame members canprovide a greater load carrying capacity of the connecting apparatus.

The upper horizontal rigidly-mounted base frame members 48 and 49 passthru the upper slidable-mounted frame members 57 and 58. The lowerhorizontal rigidly-mounted base frame members 50 and 51 pass thru thelower slidable-mounted frame members 59 and 60. The slidable-mountedframe 46 is free to laterally move with respect to the rigidly-mountedbase frame 45. All six rigidly-mounted base frame members and all fourslidable-mounted frame members are typically vertically coplanar. WhileFIG. 5 and subsequent figures show a frame made from longitudinalmembers having a rectangular or square cross-section, it is contemplatedthat longitudinal members may be formed having a cylindricalcross-sectional area such as pipes or solid rods (see FIG. 39b ). FIG. 5and subsequent figures show the square frame members turned in adiagonal horizontal position representing a diamond shape, theconnecting apparatus would also work in a similar fashion with the framemembers turned in the square position with the bottom and top of theframe members situated in a horizontal squared position (see FIG. 39a )as opposed to a forty-five degree diamond slanted position when comparedto a horizontal plane.

As depicted in subsequent drawings, (see FIGS. 13, 14, 15, 16) a lightermore economical version of the connecting apparatus 40 as depicted inFIG. 5 can be configured with only two hollow horizontal frame membersincluded in the slidably-mounted frame 46 and only four horizontal framemembers included in the rigidly-mounted base frame 45. (see FIGS. 13,14, 15, 16) In addition to the connecting apparatus as depicted in FIG.5, a larger stronger version of the connecting apparatus can beconfigured by increasing the number of horizontal frame members includedin the slidably-mounted frame to six or more (not shown) and increasingnumber of horizontal frame members in the rigidly-mounted frame to eightor more. (not shown) Also in addition to adding horizontal and verticalframe members to gain more strength and weight carrying capacity of theconnecting apparatus, using a stronger or greater diameter and thicknessof the metal used in all of the frame members will achieve a greaterweigh carrying and working capacity. For great weight carrying andworking capacity of the connecting apparatus, all of the rigidly-mountedbase frame horizontal frame members can be constructed of solid steelbars.

FIG. 6 shows a single location of top-link attachment plate 66 and twolocations of bottom-link attachment plates 68 located on therigidly-mounted frame 45, which are for attachment to the tractortop-link and bottom-link points, respectively, of the three-point hitch.Four horizontal sliding-frame members or sleeves are shown. Pushing orpulling means such as a hydraulic actuator and cylinder, electricactuator and cylinder, pneumatic actuator and cylinder, otherpositioning devices, chain, cable, belt or combinations thereof areprovided for moving the slidable-mounted frame 46 laterally and parallelto the rigidly-mounted frame 45.

For example, a single hydraulic driver 80 is mounted for the lateraladjustments of the sliding-frame 46. The hydraulic driver 80 provideslateral movement of the slidably-mounted frame 46 across therigidly-mounted base frame 45. The slidably-mounted frame 46 is free toslide laterally with respect to the base frame 45. The left-rightmovement and position of slidably-mounted frame 46 is changed by atleast one hydraulic driver 80 comprising a housing 82 and a piston 83,or optionally more than one driver, such as two hydraulic drivers 80(see FIG. 7). Typically, the driver has an internal stop for limitingthe lateral movement of the slidably-mounted frame 46. The hydraulicdriver is connected between the rigidly-mounted base frame 45 and theslidably-mounted frame 46. The cylinder housing 82 of the hydraulicdriver 80 is removably attached at one end to a bracket 90 with a pinand clip and the bracket 90 is connected to bracket 92 b which isconnected to the rigidly-mounted base frame 45 at vertical frame member56. The piston 83 of the hydraulic driver 80 is removably attached to abracket 89 with a pin and clip and the bracket 89 is connected to abracket 94 b which is connected to the slidably-mounted frame 46 at thevertical frame member 61. In this configuration, when the piston 83 ofthe hydraulic driver 80 moves out of the housing 82, theslidably-mounted frame 46 is caused to slide away from the bracket 90 ofthe rigidly-mounted base frame 45. When the piston 83 of the hydraulicdriver 80 moves back into housing 82, the slidably-mounted frame 46 iscaused to move closer to the bracket 90 of the rigidly-mounted baseframe 45. The hydraulic cylinder housing 82 has two hydraulic flexiblelines 85 attached which in turn can be attached to a tractor manualhydraulic control valve 236 and the automated hydraulic control valve238. The driver 80 can be operated manually or automatically.

The single hydraulic cylinder 80 is mounted in a centered locationbetween the top and bottom of the sliding-frame 46 for lateraladjustment of the sliding-frame 46. The single hydraulic cylindercentered design can be used when a Power Take Off “PTO” driveline is notrequired for the implement that is attached to the connection apparatusas this centered single hydraulic cylinder position would obstruct thepathway 98 of a PTO driveline (see FIG. 7) as it is connected betweenthe tractor PTO shaft and the implement to be attached to the connectionapparatus.

The driver typically has static loading capacity, meaning that when thedriver stops and reaches a predetermined adjustment point, the driveressentially locks in place and can support a load that is either pullingor pushing on the driver. Typically, in an agricultural tractorapplication, the tractor hydraulic system control valves and hydrauliccylinders are valved for a static loading capacity. Typical electriclinear actuators that are screw or gear driven generally have a staticloading capacity or an electro-mechanical brake added to provideimproved static loading capacity.

Preferably hydraulic drivers are used as compared to electric, sprocketand chain drives, pneumatic drives and electro-magnetic drives.Hydraulic actuators are rugged and suited for high-force applications.They can produce forces 25 times greater than pneumatic cylinders ofequal size. They also operate in pressures of up to 4,000 psi.

Electric motor actuator drives are weak and usually expensive comparedto hydraulic cylinder movement applications. Electrical actuators can beused, because they have fewer component parts and can provideprecision-control positioning. An example of the range of accuracy is+/−0.0003 in. and a repeatability of less than 0.00004 in. Their setupsare scalable for any purpose or force requirement, and are quiet,smooth, and repeatable. The initial unit cost of an electrical actuatoris higher than that of pneumatic and hydraulic actuators.

Sprocket and chain drives can be used, but they have slack between theparts causing less precise movement when compared to a hydrauliccylinder positioning system.

Pneumatic cylinder drives can be used but they have limited positioncontrol Electro-magnetic actuators such as linear motor actuators,although possible in this application, generally do not possesssufficient force capacity for linear movement. Linear motor actuators dohave the advantage of being able to be sealed very easily againstmoisture and corrosion allowing for a long service life. As technologyadvances, electro-magnetic actuators may be a preferred choice in manyapplications. Mechanical actuator means only of controlling the drivermay be useful in a limited number of applications using mobilemachinery.

Manual operational control of the hydraulic or electric driver can bepreferred in some applications while using the connecting apparatus. Aswitch switching between manual and automatic control of the driver canbe provided along with a manual control valve or switch. One instancewhen manual control of the driver may be utilized is when then mobilemachine operator is attaching or removing implements from the connectingapparatus. The manually operated valve or switch would provide manuallateral positioning of the connecting apparatus slidable frame forhookup of an implement. Another instance where manual operation of thedriver may be utilized is when the mobile machine operator has noautomatic guidance system setup for use or the mobile machine operatorsimply prefers the manual operation of the driver in certainapplications.

Also shown in FIG. 6 is the rear face of the double wrap-around bracketclamps 78, which are used for the opposing implement side connection.

Attachment plates 66 are mounted on the tractor facing side of therigidly-mounted base frame 45 top horizontal frame member 47 forconnection of the top-link arm 324 (see FIG. 1c ) to the tractortop-link attachment brackets 340 (see FIG. 3). Two attachment plates 68are mounted on the tractor facing side of the rigidly-mounted base frame45 bottom horizontal frame member 52 for hookup of the tractorbottom-link arms 318 (see FIG. 3) to the connecting apparatus. Top-linkattachment plates 66 includes two vertical parallel plates or flangesdefining a bracket with coaxial aligned thorough holes projectingoutward or upward from the surface of the rigidly-mounted base frame tophorizontal member 47 which provides for connecting a top-link arm 324(see FIG. 1b ) to the tractor. Bottom-link attachment plates 68 includetwo vertical parallel plates or flanges defining a bracket with coaxialaligned thorough holes projecting outward or outward and upward from thesurface of the rigidly-mounted base frame bottom horizontal member 52which provides for connecting the two bottom-link arms 318 (see FIG. 3)of the tractor to the rigidly-mounted base frame 45.

At least four grease fittings 74 for each horizontal frame member of theslidable-mounted frame 46 are provided to lubricate the sliding actionof the slidable-mounted frame 46 upon the rigidly mounted frame 45.Optimally, sixteen or more grease fittings are provided for eachhorizontal frame member of the slidably-mounted frame 46 for completecoverage of lubricant between the two frames. Grease fittings 74 areshown mounted on the slidable-mounted frame 46 screwed into threadedholes or fittings on all sliding horizontal frame members of thesliding-frame 46.

Shown in FIG. 6 are viewable rigid-frame alignment marks 70, alsoreferred to as positioning indicia, located on the upper rigid-framehorizontal frame member 47 marking the edge of the sliding-frame whenthe sliding-frame is centered on the rigid frame, the rigid-framealignment marks 70 located on the lower rigid-frame horizontal framemember 52 marking the edge of the sliding-frame when the sliding-frameis centered on the rigid frame. A rigid-frame alignment mark 72, alsoreferred to as positioning indicia, is located on the lower rigid-framehorizontal frame member 52 for marking the center of the sliding-framewhen the sliding-frame is centered on the rigid-frame. This allowscentering of the slidable frame. For the upper rigid-frame horizontalframe member 47, the rigid-frame top-link attachment plates 66 serves asa center mark. The hydraulic cylinder 80 length and rigidly-mountedframe section 45 width can be altered depending on the length of lateralmovement required of the sliding-frame section 46.

FIG. 6 shows the hydraulic lines 85 connected between the hydraulicdriver 80 and both the manual hydraulic control valve 236 and theautomatic hydraulic control valve 238. FIG. 7 show hydraulic lines 87connected between a hydraulic flow divider 88 and both the manualhydraulic control valve 236 and the automatic hydraulic control valve238. FIG. 6 and FIG. 7 show hydraulic lines 87 a connected between themanual hydraulic control valve 236 and a hydraulic valve selector switch240. Hydraulic lines 87 b are connected between the automatic hydrauliccontrol valve 238 and the hydraulic valve selector switch 240. Hydrauliclines 87 c are connected between the hydraulic valve selector switch 240and the hydraulic pump 81. Hydraulic power receptacle 242 comprisingdual quick connect couplers serve as the hydraulic power receptacle andconnect and disconnect means for the hydraulic lines when attaching orremoving the first connecting apparatus 40 from the tractor three-pointhitch.

With reference to FIG. 7, a laser receiver and a GPS antenna andreceiver module 110 e is also shown mounted on the top bar 100 a. Achoice can be made as to which receiver and controller is used dependingon the application. Both receivers normally are not used at the sametime. A GPS controller can be required to be matched to the GPS antennaand receiver module 110 e; likewise, a laser controller can be requiredto be matched to the laser receiver 110. Each receiver receives a signalfrom a transmitter and then relays a signal that can be digital oranalog or other to the controller 150 through signal wire 110 d or 110f. A data entry monitor 150 b can be provided if required to enter datato the controller such as in the case of the GPS controller. Data wire150 c is connected from the data entry monitor 150 b to the controller150. (see FIGS. 6 and 7) The controller 150 sends a signal 150 a to theautomatic hydraulic control valve 238. (see FIGS. 6 and 7) In theinstance where an electric actuator is used for the driver 80, FIG. 4bshows the configuration of the electrical components for the operationof the driver 80.

FIG. 7 shows a double hydraulic cylinder providing lateral movement ofthe slidably-mounted frame 46 across the rigidly-mounted base frame 45.The double hydraulic cylinder design can be used when a Power Take Off(“PTO”) driveline is required for the implement that is attached to theconnection apparatus, as this double hydraulic cylinder design normallydoes not obstruct the pathway of a PTO driveline as it is connectedbetween the tractor PTO shaft and the implement to be attached to theconnection apparatus. In addition, heavy loads that may be mounted onthe connection apparatus can benefit from the double hydraulic cylinderdesign by spreading out the push-pull force of the hydraulic cylindersto two locations of the sliding-frame 46 instead of one location. Theslidably-mounted frame 46 is free to slide laterally with respect to thebase frame 45.

The left-right movement and position of slidably-mounted frame 46 iscontrolled by two hydraulic drivers 80. Each hydraulic driver isconnected between the rigidly-mounted base frame 45 and the secondslidably-mounted frame 46. The housing 82 (see FIG. 6) of the tophydraulic cylinder 80 is connected at one end to the bracket 90 which isconnected to brackets 92 a which are connected to the rigidly-mountedbase frame 45 at vertical frame member 56. The piston 83 of the tophydraulic driver 80 is connected at one end to the bracket 89 which isconnected to bracket 94 a which is connected to the slidably-mountedframe 46 at vertical frame member 61. The housing 82 of the bottomhydraulic driver 80 is connected at one end to the bracket 90 which isconnected to bracket 92 c which is connected to the rigidly-mounted baseframe 45 at vertical frame member 56. The piston 83 of the bottomhydraulic driver 80 is connected at one end to the bracket 89 which isconnected to bracket 94 c which is connected to the slidably-mountedframe 46 at vertical frame member 61. In this double hydraulic driverconfiguration, when the pistons 83 of the hydraulic drivers 80 moves outof hydraulic housing, the slidably-mounted frame 46 is caused to slideaway from the bracket 90 of the base frame 45. When the pistons 83 ofthe hydraulic driver 80 moves back into the housings 82,slidably-mounted frame 46 is caused to move closer to brackets 90 of thebase frame 45. In the double hydraulic cylinder configuration, thehydraulic fluid flow divider 88 is utilized to provide even distributionof hydraulic fluid to each hydraulic driver 80, causing both hydraulicdrivers 80 to be synchronized with each other while moving in parallelto provide the lateral movement of the slidably-mounted frame 46 withrespect to the rigidly-mounted base frame 45. Hydraulic lines 86 aredisposed between each hydraulic cylinder 80 and the hydraulic fluid flowdivider 88 for even fluid distribution to the hydraulic cylinders 80while hydraulic lines 87 are disposed between the hydraulic fluid flowdivider 88 and the hydraulic control valve normally equipped on atractor carrying the connecting apparatus. The double hydraulic cylinderconfiguration can be helpful in moving the slidably-mounted frame 46when the implement to be carried by the connecting apparatus is of thelarger and heavier nature.

With reference to FIGS. 7 and 8, a top-bar first bar 100 a is rigidlyattached to the slidably-mounted frame section 46 with attachment legs101. The top-bar first bar 100 a supports (i) a laterally adjustablypositioned laser receiver 110 or a GPS antenna and receiver module 110 eprovided with an adjustable holding bracket 108 for supporting a GPS ora laser guidance system, (ii) an LED light fixture 118, and (iii)mounted camera housing 112 comprising two cameras 114 and 116 focusedrearwardly and downwardly, respectively, being mounted on a slidable bar104 for lateral adjustment. The separate viewing cameras 114 and 116 areenclosed in the camera housing 112. Top-bar 100 a has a top-bar plate100 c for the mounting of the GPS antenna and receiver module 110 e withdual antennas (see FIG. 11). The slidably-mounted frame 46 horizontalframe members and the top-bar first bar 100 a have indicia markings,also referred to as positioning indicia, laid down in inches ormillimeters thereon, to provide useful adjustment marks. Laser receiver110 has a left alignment indicator 110 a, center alignment indicator 110b and a right alignment indicator 110 c. The top-bar first bar 100 aextends laterally beyond the slidable frame 46 as is needed. Aposition-sensor 151 is attached to the-top-bar mounting leg 101. Aposition-sensor bar 151 a is attached to the rigid-frame horizontalframe member 47 with position-sensor bar attachment brackets 152, withposition sensor electrical wires 152 a extending from position sensorbar 151 a.

With reference to FIG. 7, optionally the position signal receiver 110 or110 e, such as a GPS or laser signal receiver, supported by the slidablesecond framework, can determine the position of slidable secondframework, and can provide a position signal through signal wires 110 dor 110 f the controller 150. The controller 150 is adapted to controlthe driver 80 for keeping the implement on track via the controlleroutput signal 150 a to the automated hydraulic valve that controls thedriver 80. A suitable programmed controller 150 that can provide outputsignals can be obtained from by Trimble of Sunnyvale, Calif. for eitherthe laser or GPS system.

FIG. 8 is a perspective view of the implement-facing side of theconnecting apparatus 40. The slidably-mounted frame 46 providesconnection means for most three-point hitch implements in theagricultural and earth excavating fields, such as bed shapers, seedplanters, plant transplanters, cultivators, weeders, sprayers, rippers,box scrapers and the like. The slidably-mounted frame 46 is fitted withtwo double-frame member wrap around bracket clamps 78, which are mountedto the slidably-mounted horizontal frame sleeves 59 and 60.Sliding-frame bottom-link mounting arms 132 attach to two doublewrap-around bracket clamps 78 which protrude out towards the implementto be attached. Sliding-frame bottom-link quick-hitch slip-on housing135, as described in U.S. Pat. No. 7,059,419, attach and secure over thesliding-frame bottom-link mounting arms 132. (see FIG. 23) Thebottom-link attachment points are normally spaced between 20 and 36inches apart in a centered location on the slidably-mounted frame 46 andlocated near the horizontal plane of sliding-frame member 60. Theslidably-mounted frame 46 is also fitted with a top-link quick hitchattachment point attached to the double wrap-around bracket clamp 78which is mounted to slidably-mounted horizontal frame members 57 and 58.The top-link quick hitch attachment point is normally horizontallycentered between left and right on the slidably-mounted frame 46 andadjustably located near or between the horizontal planes ofsliding-frame members 57 and 58. The two sliding-frame bottom-linkattachment hooks 136 and latching mechanism 139 combined with thesliding-frame top-link hook 130 provides for quick and easy attachmentof a three-point hitch implement such as the carry-all 300 (see FIG. 2)and serve as connectors.

The rigid-frame alignment marks 70 are located on the top rigid-framehorizontal frame member 47 marking the edge of the sliding-frame whenthe sliding-frame is centered on the rigid frame. The rigid-framealignment mark 72 located on the top rigid-frame horizontal frame member47 marks the center of the sliding-frame when the sliding-frame iscentered on the rigid frame. Rigid-frame alignment marks 70 located onthe bottom rigid-frame horizontal frame member 52 mark the edge of thesliding-frame when the sliding-frame is centered on the rigid frame. Therigid-frame alignment mark 72 located on the bottom rigid-framehorizontal frame member 52 marks the center of the sliding-frame whenthe sliding-frame is centered on the rigid frame.

With reference to FIGS. 14 and 23, there is shown the sliding-framebottom-link mounting arms 132 and rotatable ball joints 134 that arenormally located on the end of a tractor's bottom-link arms 318. (seeFIG. 1c ) Serving as the bottom connector on the sliding frame is aquick-hitch slip on housing 135 as described in U.S. Pat. No. 7,059,419.Connector 135 securely mounts over the sliding-frame bottom-linkmounting arms 132. The sliding-frame bottom-link quick hitch slip onhousing 135 and latching mechanism 139 allow for a quick hookup andrelease of the implement from the tractor bottom-link arms. Directhookup of sliding-frame bottom-link mounting arms 132 (see FIG. 14) tothe implement is a more cumbersome hookup procedure as compared to thequick hitch style of implement hookup, although this directsliding-frame bottom-link mounting arm 132 hookup may provide a moresecure and tighter fit to the implement in very precise method of useapplications. The quick hitch slip on housing 135, U.S. Pat. No.7,059,419 includes a hook means 136 open at the top and a manually orspring operated latch 139 as shown in a close up view (see FIG. 23).This close-up view shows the slip on housing slips over thesliding-frame bottom-link mounting arm 132 and is then held in place bya pin which enters the slip on housing 135 and then extends through therotatable socket and ball with axial hole of arm 132. Additionalsecuring and adjustment screws are located around the slip on housing135 for fine adjustments and a tight level fit.

With reference to FIG. 8, the top-link quick hitch attachment comprisesa top-link channel back spacer 119 to vertically align the top-linkquick hitch attachment points with the sliding-frame bottom-link quickhitch attachment points 136. An additional top-link bracket spacer 121is attached between the double wrap around bracket clamp 78 and thetop-link channel back spacer 119 to provide access to the doublewrap-around bracket clamp 78 mounting bolts. Attached to the top-linkchannel back spacer 119 is an adjustable mounting channel 122. Boltedinto the adjustable mounting channel 122 is a sliding-frame top-linkhook and stop bar 130 top-link channel side spacers 120 inserted andbolted through. The sliding-frame top-link hook 130 generally is deeperand longer than the sliding-frame bottom-link quick-hitch hook and stopbar 136, the sliding-frame top-link hook 130 does not generally performlifting functions of the attached implements, the sliding-frame top-linkhook 130 hooks under and then up to catch the top-link hookup connectionon the implement 312 (see FIG. 2) and holds the implement in place andallows the adjustment of tilting forward and backwards performed by thetractor mounted top-link arm 324. (see FIG. 1c ) Top-link arm 324 ismounted to the tractor at location 340 (see FIG. 3) and to theconnecting apparatus, and in many applications can be a double actionhydraulic cylinder performing tilting adjustments for the attachedimplement.

FIG. 9 is a perspective view of the implement facing side of theconnecting apparatus, showing the sliding-frame bottom-link housing 138attached to the adjustable mounting channel 122 which traverses the fourhorizontal frame members 57, 58, 59, 60 of the sliding-frame 46. Theadjustable mounting channel 122 attaches to two double wrap-aroundbracket clamps 78 of the sliding-frame 46. The adjustable mountingchannel 122 in this configuration can provide additional bottom-linkhigher or lower adjustments and added strength to the sliding-frame 46while allowing space for an implement PTO driveline to pass through theconnecting apparatus from the implement being carried to the tractor PTOshaft. A sliding-frame bottom-link quick-hitch bolt-on housing 138 canbe provided in place of the sliding-frame bottom-link quick-hitchslip-on housing 135, U.S. Pat. No. 7,059,419. The sliding-framebottom-link quick-hitch bolt-on housing 138 can be a more stableattachment for the bottom-link connection point to the implement of theconnecting apparatus as compared to the sliding-frame bottom-linkquick-hitch slip-on housing 135. In the alternative for connecting animplement to the connecting apparatus, the sliding-frame bottom-linkmounting arm and ball socket, bolt-on 133, as shown in FIG. 20, can beused in place of the sliding-frame bottom-link quick-hitch bolt-onhousing 138 to provide a more stable attachment of the implement to theconnecting apparatus. The position-sensor 151 sliding-frame mounted isattached to a top-bar mounting leg 101.

The position-sensor bar 151 a is rigid-frame mounted, and is attached tothe top rigid-frame horizontal frame member 47 with position-sensor barattachment brackets 152. Position sensor electrical wires 152 b and theposition sensor bar electrical wires 152 a extend from both positionsensor 151 and position sensor bar 151 a to provide the conductors forthe position sensor signal 151 b and the position sensor bar signal 151c. Optionally a wireless connection can be used. The position sensor 151and the position sensor bar 151 a can send a visual screen signal 153 efor an operator's viewable positioning screen 153 d for the tractoroperator to view the position of the slidable-frame 46 position asrelated to the rigid-frame 45 position while looking forward and awayfrom the rear three-point hitch mounted connecting apparatus. Thisallows the tractor operator to reposition the rigid-frame 45 byrepositioning the tractor using the tractors steering if the tractor isdiverging from the prescribed path. Auto-steering of the tractor canalso be utilized by configuring the position sensor 151 and the positionsensor bar 151 a with an automated auto-steer controller 153 utilizingan auto-steer controller signal 153 a sent to the auto-steer device 153b to control the steering of the tractor. The auto-steer controller canbe equipped with an auto-steer controller on-off switch 153 c to allowthe tractor operator to manually steer the tractor when necessary.

In the instance the auto-steer function is utilized, and in the instancethe tractor is to be steered in a straight line only by the auto-steerfunction, mounting the connecting apparatus on the rear three-pointhitch of a front wheel steered tractor is sufficient to keep the tractorin a straight line. In the instance a front wheel steered tractor isrequired to auto-steer in a path that is not a straight line such asturns, the connecting apparatus 40 can be mounted on the front of thetractor for precise steering along a predetermined path. In thisinstance the present apparatus 40 can be mounted on the frontthree-point hitch of the tractor and another apparatus 40 can be mountedon the rear three-point hitch of the tractor depending on theapplication and implements being used. In the alternative to mountingthe apparatus 40 on the front of a front wheel steered tractor in asituation where the predetermined path follows turns and the apparatus40 is required to be mounted on the rear three-point hitch of thetractor, a separate auto steer device can be mounted on the front of thetractor to achieve sufficient auto-steering results in a predeterminedpath following turns.

Optionally for mobile machinery equipped with an auto-steering system153 and 153 b, such as those provided by Trimble of Sunnyvale, Calif.,the position sensor 151 sensing the position of the second frameworkrelative to the first framework, can use the auto-steer system forautomatically adjusting the position of the mobile machinery based onthe sensed position of the second framework relative to the firstframework. Current auto-steering devices work by either controlling thehydraulic fluid of the mobile machinery hydraulic steering system orcontrolling the mechanical steering wheel of the mobile machinery.

FIG. 10 is a perspective view of the implement facing side of theconnecting apparatus 40, showing the adjustable mounting channel 122attached to the double wrap around bracket clamp 78 comprising a twohorizontal frame member channel mounting configuration of thesliding-frame for the bottom-link connections to the implement.

Twoviewable gauges plumb measurement 147 are mounted on the side, near thetop of each rigid-frame vertical frame member 53 and 56. One auto-sensorgauge level measurement 148 is mounted on one of the gauge mountingplates 145 situated on the rigid-frame horizontal frame member 47. Oneauto-sensor gauge plumb measurement 149 is mounted on the side, near thetop of rigid-frame vertical frame member 53. The auto-sensor devices canautomate the level and plumb positions of the connecting apparatusutilizing the tractor installed hydraulic positioning of the tractorsthree-point hitch. This automated leveling and plumbing of theconnecting apparatus requires the tractor three-point hitch toaccommodate controlled hydraulic cylinders at the top-link arm 324 andon at least one of the bottom-link arms 318.

A bottom-bar 140 is mounted on the bottom of the slidable-mounted frame46 and below the sliding-frame bottom-link 138, and below a doublewrap-around bracket clamp 78 being securely fastened to theslidable-mounted frame 46 with bottom-bar mounting legs 142. Bottom-barsensor or cameras 144 are securely mounted to the underside of thebottom-bar 140, in the case of sensors, for the detection of electronicsignals transmitted from an underground buried cable in which theslidable-mounted frame 46 adjusts laterally to follow the path of thesignal transmitted from the underground buried cable. In the case ofcameras, recognition computer software can be used to detect theposition of crops or other items like line markers or shapes to adjustthe slidably-mounted frame 46 in position. Bottom-bar signal wire 144 acan transmit the signal to controller 150 (see FIG. 6) utilizing thesame configuration of controller and related equipment as shown in FIG.6.

FIG. 39c shows independently controlled wing sections 221 that attach tothe left and right side edges of the rigidly-mounted base frame 45 ofthe connecting apparatus 40. The wing sections 221 comprise their ownrigidly-mounted base frame 45 and their own slidably-mounted frame 46.All three slidably-mounted frames 46 move independently of each other.The wing sections 221 can be utilized for carrying lighter dutyimplements such as weeders, sprayers, cutters and the like. The wingsections 221 attach to the three-point attached first connectingapparatus 40 using a hinge. A piano style hinge 230 can be a suitablepreferred attachment device to utilize for the attachment and pivotingaction of the wing section 221 as connected to the three-point attachedfirst connecting apparatus 40 left and right side edges. Attachmenthardware 224 and 226 allows for a push pull means such as a hydrauliccylinder 228 to be mounted on the first connecting apparatus 40 and oneach wing section 221 at the joining corners at the top and bottom ofthe three rigidly mounted frame sections 45. Each wing section 221pivoting action can be controlled separately apart from the opposingwing section allowing for individual control of the wing sections. Twohydraulic cylinders 228 for each wing section 221 can work in tandemusing a hydraulic fluid flow divider 232 between the hydraulic cylinders228 and the tractor mounted hydraulic control valve 234. For control ofthe slidably mounted frames 46 on each wing sections 221, the wingsection driver 80 can attach directly between the rigidly mounted firstframe 45 and the slidably mounted frame 46 using the attachment bracket89 to the driver 80 piston arm and the attachment bracket 90 to thedriver 80 cylinder housing. The mounted position of the driver 80 on thewing section differs from the mounting position of the driver 80 on thefirst connecting apparatus 40. This difference is the result of theoffset positioning of the wing section 221 slidably-mounted frame 46 asmounted on the rigidly mounted first frame 45.

Shown are hydraulic fluid lines 84 from the hydraulic control valve 234leading to a hydraulic power pump 81, and showing the hydraulic fluidlines 86 from the hydraulic cylinder 228 to the hydraulic flow divider88 and showing the hydraulic fluid lines 87 from the hydraulic flowdivider 88 to the hydraulic control valve 234.

For hydraulic or electrically powered devices for driving the secondframework of each wing section 221, such as a hydraulic or electricallypowered cylinder, or for locally pumped fluid, a power receptacle can beprovided on the first framework 45 of the first connecting apparatus 40,or alternatively on the mobile machinery. The power receptacle canreceive hydraulic fluid or electrical power such as DC or AC power. Forhydraulic or electrically powered devices for driving the secondframework of the first connecting apparatus 40, such as a hydraulic orelectrically powered cylinder, or for locally pumped fluid, a powerreceptacle can be provided on the mobile machinery. The power receptaclecan receive power such as hydraulic fluid or DC or AC power.

Each wing section 221 slidably-mounted frame 46 is mounted in an offsetposition on the wing section rigidly-mounted base frame 45 to allow forthe implements attached to the wing section 221 to extend past the outeredge of the wing section 221, thereby allowing for the implementsattached to the first connecting apparatus 40 to extend partially acrossand into the horizontal plane of the wing section 221. This allows for acultivating or other farm work path of approximately sixty feet in widthwhen utilizing three independently moving twenty feet wide implements.The outer wing section 221 sliding frames 46 move independently of eachother and independently of the first connecting apparatus 40 slidingframe 46. This independent motion of the sliding frames allows for afarmer to till, bed-shape and plant crop sections of the farmland intwenty-foot wide sections using the first connecting apparatus 40 withattached implements and then mount the lighter weight wing sections 221to the first connecting apparatus 40 for the use of lighter weightimplements that can traverse two additional twenty-feet wide cropsections for less strenuous implement activities such as weeding,spraying and harvesting. The independent motion of the wing section 221sliding frames 46 allows the wing section 221 sliding frame 46 to followtheir own particular section of the crop rows as that particular sectionof crop rows was planted by a guidance system independently of the othercrop row sections in the sixty-foot total area covered, variancesbetween the twenty-foot sections of crops rows throughout the farmoccur. Conversely, if a sixty-foot continuous implement is attached tothe first connecting apparatus 40 sliding-frame 46 with no independentlycontrolled wing sections attached and traversing three twenty footsections of crop rows and the twenty-foot sections of crop rows asshaped and planted independently of each other as many farmers practicecurrently, the sixty-foot continuous implement may not align properlywith all of the planted crop rows resulting in damaged crops in afarming procedure such as weeding.

Functionality of the Related Parts of the Connecting Apparatus:

The receiver 110 or 110 e provides the present position of theslidable-frame 46 to a GPS controller or laser beam fixedly located inthe field. The GPS controller or laser beam contains the coordinatesdescribing the desired field position of the implement attached to theslidable-frame 46 at any one time. If the slidable-frame 46 and theimplement being carried are out of position, the GPS signal or laserbeams signal, after being received by the receiver-110 or 110 e, directsthe driver controller 150 to position the driver 80 to keep theimplement which is attached to the connecting apparatus on theprescribed path using the hydraulic controls on the tractor theapparatus 40. The piston of the hydraulic cylinder 80 moves theslidable-frame 46 laterally to the desired position as the tractor movesalong.

A GPS controller is typically a microprocessor that receives GPSsignals, compare the received signal to preprogrammed desiredcoordinates, and outputs a signal based on the difference, if any,between the desired coordinates and the received position. Such GPScontrollers are conventionally used for controlling tractor steering. Aconventional GPS guided steering system for tractors is available fromTrimble of Sunnyvale, Calif. One popular GPS guidance system currentlybeing used in the agricultural industry is called Real-Time Kinematic(RTK). RTK systems when combined with earth mounted base stations usingradio or cellular signals relayed to the roving mobile machinery withina prescribed radius location can achieve horizontal accuracy of <4centimeters in most conditions. Laser guidance and wire signal guidanceare also viable guidance system technologies available for the controlof the present invention apparatuses. A laser guidance system normallyuses a vertical spinning laser transmitter to be received by the laserreceiver mounted on the apparatus top bar 100 a or 100 b. The laserreceiver 110 then transmits a signal to the controller 150 which thencontrols the driver 80 and the position of the sliding frame 46 of thecontrolled apparatus 40. A wire signal guidance system involves multiplesensors mounted on a bottom bar for a buried wire and on the top bar foroverhead wires. The bottom bar 140 sensor mounted system normally isutilized in open field agriculture while the top bar 100 b mountedsensors system normally is utilized in greenhouse agriculturalapplications.

The lateral position of the sliding frame with respect to the centerline of the base frame and forward movement of the tractor can beadjusted by causing the pistons of the hydraulic cylinder 32 to extendor retract.

The control of the hydraulic cylinder 80 can be implemented in manualmode by the driver, a second individual, or automatically in automaticmode by a controller including sensors monitoring the position of thethree-point hitch attached implement with respect to a known desiredposition for the implement.

A system according to this invention comprises the mobile machinery suchas a tractor having a three-point hitch, the connecting apparatusattached to the mobile machinery with the three attachments; and animplement attached to the slidable second framework with at least threeconnectors. To connect the apparatus to the implement, the implement andapparatus are placed proximate to each other; the alignment of theconnectors and the hitches are determined, and the alignment is adjustedby sliding the second framework relative to the first framework.

After attachment of the implement to the connecting apparatus iscompleted, during use of the system, the position of the implementrelative to the mobile machinery is adjusted by the mobile machineryoperator in manual mode or by the signal receiver 110 or 110 e and thedriver controller 150 in automatic mode, changing the position of thesecond framework to keep the implement on track.

The driver 80 can be powered hydraulically or electrically. FIG. 4a is aflow chart depicting a hydraulic driver and related components suitablefor use with the present invention. It utilizes mobile machineryhydraulic pump 81, which is normally used for controlling thethree-point hitch link arms 318 and 324 (see FIG. 3) and utilizes afluid reservoir. A guidance signal is received by the receiver 110 or110 e which is connected to the driver controller 150. The antenna (notshown) is optionally provided to enhance the reception of the guidancesignal to the GPS receiver 110 e, but not requires for a laser receiver110. The driver controller 150 transmits a signal to the automaticdouble action hydraulic valve 238 to control the driver 80. If thehydraulic valve option switch 240 is in the automatic position, theautomatic double action hydraulic valve 238 controls the driver 80. Ifthe hydraulic valve option switch 240 is in the manual position, theautomatic double action hydraulic valve 238 does not receive hydraulicfluid and is not operational, and thus the manual double actionhydraulic valve 236 controls the driver at the tractor operator'sinitiation. Hydraulic power receptacles 242 provide connect anddisconnect locations for the hydraulic lines leading from the hydraulicfluid valves to the driver 80 for connection and removal of theapparatus from the three point hitch of the mobile machinery.

Electrical power from the mobile machinery battery is used for poweringthe drive controller 150 and signal receiver 110 or 110 e.

FIG. 4b is a flow chart depicting an electric driver and relatedcomponents of the present invention apparatuses. As in the hydraulicversion, a guidance signal is received by the receiver 110 or 110 ewhich then transmits the signal to the driver controller 150. The drivercontroller 150 sends a signal to an automatic electric switch 248 tocontrol the driver 80. If an electric option switch 250 is in theautomatic position, the automatic electric switch 248 controls thedriver 80. If the electric option switch 250 is in the manual position,the automatic electric switch 248 does not receive electric current andis not operational, therefore allowing the manual electric switch 246 tocontrol the driver at the tractor operator's initiation. Electric powerreceptacles 244 provide connect and disconnect locations for theelectrical conductors leading from the electric switches to the driver80 for the connection and removal of the present invention apparatusesfrom the three point hitch of the tractor.

A typical method of using the invention for agricultural comprises:

1. Choose a guidance system:

-   -   a. Manual or automatic.    -   b. If manual, choose single tractor operator or double tractor        operator. (Double operator—first operator steering the tractor        and the second operator manually controlling the apparatus        driver 80).    -   c. If automatic, choose GPS guided, laser guided, guidance wire        guided or other.    -   d. If automatic is chosen, the guidance system must be set up        and installed.

2. Row and raised bed crops utilizing the guided system with all stepsfor any or all of the following:

-   -   a. Precision tilling or preparing the soil for planting.    -   b. Precision position spraying of herbicides and/or insecticides        prior to planting if required.    -   c. Precision laying or dropping fertilizer if required.    -   d. Precision position installing drip tape if required.    -   e. Precision position installing of mulch or plastic culture if        required.    -   f. Precision position planting of seeds or transplanting        seedlings.    -   g. Precision position spraying of herbicides and/or insecticides        after planting if required.    -   h. Precision position weeding with soil cultivation or weed        cutting when required.    -   i. Precision position harvesting.

The invention can also be used for earth excavating and grading.

Among the advantages of the invention with a guided system are:

-   -   a) The horizontal adjustments of the present invention provide        an accurate system of obtaining the desired path of excavation        and soil preparation as compared to utilizing an automated        steering device of the mobile machinery as the only form of        implement path guidance.    -   b) Utilizing mobile machinery steering guidance combined with        mobile machinery implement guidance creates a more accurate        system of obtaining the desired path of excavation and soil        preparation as compared to utilizing an automated steering        device of the mobile machinery as the only form of implement        path guidance.
